Specification of Letters Patent. Application filed June 28. 1906. Serial No. 323.849.

Ea'tented March 3, 1908.

T 0 all whom it may concern:

Be it known that we, MORTON DECKER and MARVIN H. MATTY, both citizens of the United States, residing, respectively, atChicago and Clayton, in the counties of Cook and J efierson, and States of Illinois and New York, have inventedcertain new andusefu an we do hereby declare the following to be a full, clear,- and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in cream separators, and more especially to driving mechanism therefor The object of our invention is to provide a simple driving mechanism for a cream separator with the gearing contained in a removable gear case permitting theuse of a sprocket chain drive inside the casing with a. low down milk supply tank, whereby the milk may be readily fed into the top of the bowl. y l y With these objects in view, our invention consists in the constrifiztion and combination of parts as hereinafter described and claimed.

In the accompanying drawin s; Figure 1.

is a side view of our improve invention. Fig. 2 is a similar view with the frame and gear casing shown in section. Fig. 3 is a side view of the removable gear case, and Fig. 4 is an end view of the same.

(t represents the supporting frame, which consists of a hollow metal casting elli tical in its eneral outline, and adapted to be fastened olts b to the floor, or other suitable support. The top of this frame is closed by a removable cover 0. In the top of the frame is j ournaled a shaft 1, which is provided with a driving crank c, and on the shaft 11 is mountover which a sprocket chain g passes, said chain small sprocket wheel h '1' ournaled on a shaft '1' on the rerr'iovab'lev gear casing 7'. This re movable ear casing is shown detached in Fig. 3. t is of such a size as to extend nearly across the frame a, and is provided with a boss is, which is adapted-to enter a perforation in the frame a. This boss is. screw threaded for there'ception of a headedscrew m, and when this screw is turned home the ear case is firmly held in the frame a, a

ange n being provided, which fits against the side of the frame 1'. The upper part of the gear casing is provided with a removable cover 0, whichcover is provided with a flange 9 fitting down within the main portion of the gear case, and held iriplace by the frame a, when the gear case is inserted in said frame. On the shaft i,- which carries the sprocket wheel 72., is-journaled a gear wheel g, which meshes with a small gear wheel 1*, on the shaft s, journaled in the gear casing. The shaft 8 I carries a larger gear wheel t, which engages with the spirally arranged gear u on the shaft 0) of the separator proper. A nut 10 on the lower end of theshaft v keeps the latter in place. The separator bowl ac, provided with the cream and milk pipes 'y and 2, is supported in any suitable way,'as by an anti-friction ball bearing in the casing 1 attached to the side of the frame a.

2 represents an automatic oiling device, which sup lies oil to the separator bearin which oil drips down the spindle 1;, thus a ford ing a means for oiling'the gears in the case 1'. The gear wheels are thus thoroughly lubricated as they throw the" oil from one to the other, the cover 0 serving to keep the oil from being thrown out of the gear case.

3 representsthe metallic can, which communicates by means of a pipe 4 with the top of the separator as. The s indlev is so arranged that itcan be eas' y detached from the se arator, andxafter it has been so detache and the sprocket chain g disengaged from the sprocket wheel h, the whole gear case 3' containing the driving gear can be readily removed from the frame a purpose of cleaning or adjustment, and as readily replaced. The construction described has the further advantages that the sprocket chain 9 is completely covered when in use, thus avoiding hability of accidents, and the milk can 3 can be made-low down and located close to the separator, feeding into the top thereof.

Having thus described our invention, -what we claim as new and desire to secure by Letters Patent of the United States, is z- 1. The combination of a hollow metal casting provided with oppositely placed openings of different sizes,.a separator supported by said casting, a removable gear cas ing containing the driving gear for said separator, said gear casing being provided with a projection for,engaging the smaller opening in said casting and with a shoulder adapted to fit against, said casting, said gear casing being adapted to be slipped into the larger openingiiin sai casting, means for securing for the said gear casing in said casting, and means for operating the gearing in said casing, substantially as described.

2. The combination. of a hollow metal casting provided with two openings of differ ont placed eppof I to each. other, a removable casing rm driving gear and. provided witl'i a 1 a projection, means for fast casing in said casting, a sepe ape) red on said casting and provider 1 o, spindle ren'iovably connected theret 'd carried by said gear casing, a milk can pported by said casting at a higher level than said separator, and means for operating the ge i in said removable gear casing, suli stantially as described.

3. The combination of a supporting frame consisting of a hollow metal frame, provided with a large opening; and a small opening placed opposite each other, removable cover for said casting, a separator supported by said frame, a reiirirwable casing containing the driving gear for said separator, said casing being provided With a projection adapted ,to fit into the 5 .1"" iller rqiening in the supporting frai'ne, and i d casiri, .eiiig also adapted to be slipped into the larger opening in said,

frame, a sprocket wheel on the outside of' said gear casing, an operating crank, a sprocket wheel operated by said crank, a sprocket chain connecting said sprocket Wheels,anda milk can supported by said frame at a higher level than said separator, said separator being'provided With a detachable spindle, which spindle is carried by said gear casing, substantially as described. I In testimony whereof, We affix our signatures, in presence of witnesses. t
